Coevolution

Definition

noun

Two or more species having a close ecological relationship evolve together such that one species adapt to the changes of the other, thereby affecting each other's evolution.


Supplement

For instance, at microscopic level, the genes of interdependent species are found to evolve together. At macroscopic level, the traits of interdependent species co-vary over time. For example is the coevolution of insects and flowers they pollinate or the coevolution between predators and their prey.


Word origin: co-, together + evolution.

Natural selection is proven wrong

... inheritable switches to produce males being passed on, then later the unused genes lose their function or take on a new one. What you call "coevolution" would then occur between the sexes, which in turn accounts for the current special-fit machinery. As long as one can reasonably recognize ...

Evolution of Parasitoids

... is not much of a leap; from deposit of eggs on dead or debilitated hosts to lively ones isn't a huge leap. Once you've got a parasite and host, coevolution is pretty much a given.

Re: coevolution of the genetic code

PS: The genetic code represented in a circular fashion following 2-1-3 rules and applying the AGCU motif has been published in the Journal of Theoretical Biology. (Please quote: Pohlmeyer R. The genetic code revisited. J Theor Biol. 2008 Aug 7;253(3):623-4. Epub 2008 May 1. )

nucleic acid + amino acid -> genetic code

... by training so I'm a bit rusty on Darwinian terminology. I believe that like the term genetic code can be used for two different things, coevolution can mean different things to different people. Whilst I agree that a nucleic acid did not directly change the molecular structure of an ...

coevolution of the genetic code

... based upon available amino acids, with expansion later, and an expansion from a 2- to 3-base codon, are complementary. But what's explained isn't coevolution, it's adaptation - there isn't a second participant in the dance. The additional amino acids wouldn't have evolved on their own in response ...
